I was wondered a big popularity of shot-cut Nikon’s SLR D40 and 10-megapixels Nikon D40x. For more about Nikon D40x look at Canon EOS400/XTi, Nikon D40x and Pentax K10 pros& cons; SLR over SLR-like triple benefits. But when I was surfing in the Net and was talking with salesmen I saw that a lot of users want to have a small and cheap Nikon’s SLR. Other users were buying D40 such as second SLR (first is Nikon too). It is natural that majority of new Nikon’s users love their first SLR cameras. And it’s unreal to have some critical points from them. Especially it’s unreal to have some critical points from those who chose Nikon long time ago and bought second Nikon. But there are two bad points which were significant even for Nikon’s fans: the AF is not good on moving targets and the majority of Nikon’s lenses can’t work with D40 and D40x. Only special lenses are recommended for those SLRs.10-20mm F4-5.6 EX DC HSM ultra-wide zoom lens has a wide angle of view from 102.4 - 63.8 degrees and it is exclusive to digital SLR cameras. Lens construction includes 14 elements in 10 Groups and with three Special Low Dispersion glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. Hyper Sonic Motor equipped models makes fast AF speeds and quiet shooting a reality and it is also capable of full-time manual focus. Sigma 10-20 mm F4-5.6 EX has a minimum focusing distance of 24cm / 9.4inch at all focal lengths. Lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with APS-C size image sensors of digital SLR cameras. Lens dimensions 83.5 x 81mm, weight 470g. It costs $500.12-24mm F4.5-5.6 EX DG lens offers a minimum focusing distance of 28cm/11inch at all focal lengths. The super-wide angles useful range of view offers the photographer greater freedom of expression. Lens construction includes 16 Elements in 12 Groups. Four Special Low Dispersion glass elements are provided for effective compensation of color aberration, which is a common problem with super-wide angle lenses. This lens is equipped with a fixed Petal-type hood to obtain a superior extraneous light-blocking effect and with Hyper Sonic Motor (HSM) for Sigma, Nikon and Canon. Except fish-eye lenses, this super-wide angle lens is the only lens that has 12mm focal length and can be used with Digital SLR cameras as well as film SLR cameras. Lens dimensions 87 x 102.5mm, weight 600g. It costs $690.17-35mm F2.8-4 EX DG ASPHERICAL HSM super wide-angle zoom lens with a large aperture is specially designed to suit the characteristics of digital SLR cameras. It has a minimum focusing distance of 27cm / 10.6inch at all focal lengths, and maximum magnification ratio of 1:4.5. Lens construction includes 16 Elements in 13 Groups with Special Low Dispersion Glass which is used for effective compensation of color aberration. Two pieces of molded glass Aspherical lens elements offer excellent correction for distortion as well as all types of aberration. 17-35mm F2.8-4 lens has Angle of View 103.7 - 63.4 degrees. Its HSM provides quiet, high-speed autofocus shooting, as well as full-time manual focus. Lens dimensions 83.5 x 88.7mm, weight 560g. It costs $480.Sigma APO 50-150 mm F2.8 EX DC HSM is specially designed for digital SLR cameras with an APS-C size image sensor large aperture F2.8 lens. It has a minimum focusing distance of 100cm / 39.4inch. Maximum magnification of 1:5.3 enables close-up photography. Sigma APO 50-150mm is very convenient for taking close-up pictures. Lens construction includes 18 elements in 14 Groups; four Special Low Dispersion glass elements are used for utmost correction of chromatic aberrations. Hyper Sonic Motor ensures quiet and high-speed auto focusing with full time manual focus override. Vignetting will occur if APO 50-150mm is used with digital cameras with image sensors larger than APS-C size. Its Angle of View is 27.9 - 9.5 degrees, dimensions 76.3mm / 3.0inch x 132.6mm /5.2inch, weighing 780g / 27.5oz. Lens cost $679.Sigma 30 mm F1.4 EX DC HSM is a fast large maximum aperture of F1.4 specially designed for Digital SLR Cameras lens. Lens construction includes 7 Elements in 7 Groups with Special Low Dispersion and Extraordinary Low Dispersion glass elements which are used to obtain the best possible correction for magnification and chromatic aberrations, which are particular problems for digital cameras. From 40cm / 15.7inch minimum focusing distance to infinity, this lens creates very sharp images with high contrast and high-speed auto-focus shooting with HSM. Its Angle of View is 45 degree, dimensions 76.6 x 59mm, weight 400g. Lens cost $430.Look through these lenses (especially its prices). I think that Nikon D80 for $859 is much preferable for these Sigma lenses than Nikon D40 for $518 or Nikon D40x for $635. Look through Sony A100 vs Nikon D80 more worthy than Sony A100 vs DSC-H9/H7.And there isn’t Telephoto Zoom lenses for more than $1000 in this post. I will write about lenses such as Sigma 120-300 mm F2.8 DG for $2700 in my next post. And I think that cheap (short-cut) Nikon with only special (expensive) lenses is nonsense. But it’s only my opinion.

Nikon D80 has 11 autofocus zones and they can be grouped for dynamic focus while controlling the general area of interest. Nikon D40x has only three on the horizontal. Nikon claims that this would not make any difference to most users, but I have found the top and bottom zones quite helpful and would not like to do without them. In my opinion if a lot of money is not an issue for you, get only D80.
